Prime Minister David Cameron wants all British citizens to tell their Internet service providers (ISPs) whether they'd like to opt in for filters on their computers and mobile devices. Once a household chooses to use the filters, they are applied to every computer and mobile gadget used in the home -- and they can't be turned off by the child. An adult must call their ISP and disable the filters themselves.

This is just one step in Cameron's plans to keep children from being able to easily access pornography online. He also wants to reduce the number of rapes and abuse cases against women, which can be triggered by violent pornographic material found on the Internet.

Cameron is expected to discuss a new set of measures to accomplish a more porn-free Britain, including banning the distribution and ownership of "extreme pornography," such as violence and fake rape scenes; offering stronger filters through ISPs, and attempting to target pedophiles and rapists by creating a blacklist of search terms (which will pinpoint those who use the search terms) and allowing police forces to work with one secure database of illegal images.

Cameron sees pornography as being a bad influence on both children and "sick" adults who search for the wrong things, and hopes these new rules will deter any foul play.

Cameron has even addressed huge Internet companies like Google and Microsoft in his quest for a better Web experience for British residents.

"I have a very clear message for Google, Bing, Yahoo and the rest," said Cameron. "You have a duty to act on this – and it is a moral duty. If there are technical obstacles to acting on [search engines], don't just stand by and say nothing can be done; use your great brains to help overcome them.

"You're the people who have worked out how to map almost every inch of the Earth from space; who have developed algorithms that make sense of vast quantities of information. Set your greatest brains to work on this. You are not separate from our society, you are part of our society, and you must play a responsible role in it."

Last year, the UK introduced the Online Safety Bill, which aimed to force internet service providers (ISPs) and mobile network providers to offer internet packages that exclude access to pornographic material by default.

Some UK ISPs agreed to enforce the opt-in option for pornographic material as early as last year. TalkTalk Telecom Group PLC was one of the first to agree, and now, Cameron is looking to make this a widely-used method.
